Let us examine how the vehicle speed affects the number of accidents and the likelihood of death on the road, and focus on the interaction between vehicles and pedestrians as two “most opposite” traffic participants.
Speed ??and the probability of an accident
Let’s consider the stopping distance. It can be calculated if you know the driver reaction time and the stopping distance of a vehicle after the brakes have been applied.
The average reaction time is 1 second. If the speed increases, the distance travelled per 1 second also increases. The distance traveled from the moment when the brakes were applied to the moment when the car came to a full stop is proportional to the square of the speed of the car. When increasing the speed from 50 km/h to 80 km/h, the braking distance increases by 2 times. So it becomes harder to avoid hitting.
The fact that wet conditions increase the stopping distance by 25% should also be taken into account. That is, the braking distance of a vehicle driving 60 km/h on a wet asphalt road is equal to the one of the vehicle driving 70 km/h on a dry road.
When driving 80 km/h the reaction distance is about 22 meters. And on a dry road the driver will need a minimum of 36 meters to stop the car completely.
If a child runs out into the road at a distance of 36 meters from the car, it will almost certainly die if the initial speed of the vehicle will be 70 km/h, it will be injured at a speed of 60 km/h, and at 50...
